Description

Technical Field

[0001] The present invention relates to the technical field of monitoring equipment, and in particular to a distribution room environment monitoring device. Background Art

[0002] The monitoring system mainly consists of two parts: front-end equipment and back-end equipment. The front-end equipment usually consists of components such as cameras, manual or electric lenses, pan / tilt heads, protective covers, monitors, alarm detectors and multi-function decoders. They each perform their duties and establish corresponding connections with various devices in the central control system through wired, wireless or optical fiber transmission media. The distribution room needs to be installed with monitoring equipment for monitoring. Since the distribution room is mostly located on the lower floors with relatively high humidity, the loading boxes of the monitoring equipment are mostly equipped with desiccants, which absorb moisture to dry the air inside the equipment. However, the existing desiccants need to be manually replaced after a period of use to ensure the normal working environment of the electrical components in the equipment. Manual replacement is relatively cumbersome and requires repeated disassembly of the equipment casing, which can easily damage the equipment.

[0003] In order to overcome the above problems, some technical solutions for drying the air in the monitoring equipment for easy replacement have also appeared in the prior art. For example, a Chinese utility model patent with application number 2021201574901 discloses an environmental monitoring device for a distribution room, including a protection box, a first placement plate, a camera body, a placement frame, a second placement plate, a discharge pipe and a discharge assembly. The first placement plate is fixedly connected to the protection box and is located inside the protection box. The camera is detachably connected to the protection box and is located above the first placement plate. The second placement plate is fixedly connected to the protection box and is located inside the protection box. The placement frame is slidably connected to the protection box and is located above the second placement plate. The discharge pipe passes through the outer wall of the protection box. The discharge assembly is fixedly connected to the protection box and is located below the protection box. The above-mentioned structure is arranged so that when the desiccant absorbs moisture to saturation, it is convenient for the staff to replace the desiccant;

[0004] However, in actual use, this technical solution still requires manual replacement, and only simplifies the replacement steps. For example, in the humid southern region during the rainy season, the air humidity is high, especially for monitoring equipment installed in the basement, the humidity is even higher, and the desiccant adsorption saturation frequency is accelerated. The application of this technical solution in this environment still requires further manual processing, replacement and maintenance, which makes the labor cost high and increases the labor intensity of maintenance personnel. If the replacement is not timely, the normal use of the equipment cannot be guaranteed.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figures 1 to 7 , the present invention provides a technical solution:

[0039] A distribution room environment monitoring device includes a device box 1 and a camera body 18 located inside the device box 1. A mounting hole 11 is opened in the middle of the front face of the device box 1. The front face of the camera body 18 is fixedly connected to a camera 12. The camera 12 extends to the outer surface of the device box 1 through the mounting hole 11. The interior of the device box 1 is fixedly connected to a carrier plate 19. The camera body 18 is fixed to the upper end face of the carrier plate 19. The interior of the device box 1 is located on the lower side of the carrier plate 19. There is a drying mechanism 4, and a ventilation groove 15 is opened on the lower side of the front end surface of the equipment box 1. The inside of the ventilation groove 15 is rotatably connected to a fan 14. A filter 13 is provided on the front side of the fan 14. The middle part of the fan 14 is fixedly connected to a transmission shaft 16, and the other end of the transmission shaft 16 passes through the rear end inner wall of the equipment box 1. The filter 13 is fixed to the inner wall of the ventilation groove 15. The rear end surface of the equipment box 1 is provided with a transmission mechanism 5, and the transmission mechanism 5 is transmission-connected to the transmission shaft 16 of the fan 14 and the drying mechanism 4.

[0040] By adopting the above technical solution, the present invention designs the drying mechanism 4 and the transmission mechanism 5. In actual use, compared with the existing technology, there is no need for frequent manual replacement of the desiccant, which reduces the frequency of frequent disassembly and assembly of the equipment, greatly improves the drying effect inside the device, and reduces the chance of the equipment being damaged by moisture intrusion in a humid environment.

[0041] As an embodiment of the present invention, Figure 2 and Figure 3 As shown, the drying mechanism 4 includes three groups of rollers 41 distributed inside the equipment box 1, and the three rollers 41 are distributed in a triangular shape inside the equipment box 1, and both ends of the rollers 41 pass through the inside of the equipment box 1 and are rotatably connected to the equipment box 1 through bearings. The rear end of the roller 41 located at the bottom end of the equipment box 1 is connected to the transmission mechanism 5, and the outer surfaces of the three rollers 41 are wrapped with a conveyor belt 43. A number of strip-shaped drying components are equidistantly distributed on the outer surface of the conveyor belt 43, and the drying component includes a shell 42 glued to the conveyor belt 43, and the interior of the shell 42 is filled with silica gel desiccant 44 particles. The conveyor belt 43 is made of high-temperature resistant rubber material, and the shell 42 is made of elastic metal material. The shell 42 and the conveyor belt 43 are both hollow structured, and the hollow aperture is smaller than the particle size of the silica gel desiccant 44 particles.

[0042] The heating plates 3 are fixedly connected at an angle on both sides of the inner bottom of the equipment box 1. The heating plates 3 correspond to the conveyor belt 43, and the inclination angle of the heating plates 3 is consistent with the inclination angle of the conveyor belt 43 at the corresponding position. A heat insulation component 2 is provided on the lower side of the equipment box 1.

[0043] By adopting the above technical solution, when the equipment is in normal working state, the transmission shaft 16 and the drying mechanism 4 are driven to operate by the external driving device in conjunction with the transmission mechanism 5. During normal operation, the fan 14 rotates counterclockwise to introduce the outside air through the ventilation slot 15 and filter it into the equipment box 1 through the filter screen 13. Then, the air inside the equipment box 1 is ventilated and alternately heated and cooled with the outside cold air to cool the camera body 18. When the outside gas enters the equipment box 1, it will first contact the drying mechanism 4, and the hollow structure of the conveyor belt 43 and the silica gel desiccant 44 inside the shell 42 are used to dry the air entering the equipment box 1. The shell 42 absorbs moisture from the water in the water to avoid excessive moisture from adhering to the outer surface of the equipment box 1 and the camera body 18 to damage the equipment. When the water content of the silica gel desiccant 44 reaches a certain proportion, the user drives the external driving device in conjunction with the transmission mechanism 5. The driving roller 41 rotates counterclockwise, thereby causing the conveyor belt 43 wrapped around the outer surface of the roller 41 to rotate, and then the heating plate 3 and the external power supply are conductively operated to heat the air inside the equipment box 1, and then the conveyor belt 43 rotates to carry the shell 42 and the silica gel desiccant 44 filled inside. The shell 42 circulates through the heating plate 3 areas on both sides, and then dries and regenerates the silica gel desiccant 44 particles until the silica gel desiccant 44 is regenerated and the rotation of the roller 41 is stopped. The present invention is designed to cooperate with the heating plates 3 on both sides. In actual use, compared with the prior art, there is no need for manual frequent replacement of desiccant, which reduces the frequency of frequent disassembly and assembly of the equipment. The silica gel desiccant 44 particles that absorb moisture are dried and regenerated by the heating plate 3 and recycled, which greatly improves the drying effect inside the device and reduces the chance of damage to the equipment by moisture intrusion in a humid environment.

[0044] As an embodiment of the present invention, Figure 2 and Figure 4 As shown, the thermal insulation assembly 2 includes a reel 21 and a reel 23 correspondingly distributed on both sides of the equipment box 1, wherein the centers of the front and rear ends of the reel 23 are fixedly connected to the pre-tightening cylinder 22, and the two sides of the equipment box 1 are provided with extension openings 28 at positions corresponding to the reel 21 and the reel 23, and the reel 21 and the reel 23 are provided with openings at positions corresponding to the extension openings 28 of the equipment box 1, the reel 23 is internally connected to the reel rod 24 for rotation, and the reel 21 is internally connected to the reel rod 25 for rotation. Both ends of the unwinding rod 24 extend to the interior of the pre-tensioning cylinder 22 and are rotatably connected to the unwinding cylinder 23 and the pre-tensioning cylinder 22. A heat insulating member 26 is wound around the outer surface of the unwinding rod 24. The heat insulating member 26 extends from the opening of the unwinding cylinder 23 through the extension opening 28 on the outer surface of the equipment box 1, passes through the lower side of the internal load-bearing plate 19 of the equipment box 1, and extends from the extension opening 28 on the other side of the equipment box 1, extends through the opening on the outer surface of the winding cylinder 21 to the interior of the winding cylinder 21, and is fixedly connected to the outer surface of the winding rod 25 inside the winding cylinder 21.

[0045] A coil spring 221 with a spiral structure is provided inside the pre-tightening cylinder 22, one end of the coil spring 221 is fixed to the inner wall of the pre-tightening cylinder 22, and the other end is fixed to the outer surface of the unwinding rod 24 extending inside the pre-tightening cylinder 22. The rear end of the winding cylinder 21 is fixedly connected to the drive motor 27, and the output shaft of the drive motor 27 is fixed to the winding rod 25.

[0046] The thermal insulation component 2 includes a grid layer 261 and a thermal insulation film layer 262, the grid layer 261 is made of elastic metal material and is located on the lower side of the supporting plate 19 in a silent state. The sizes of the grid layer 261 and the thermal insulation film layer 262 are both larger than the size area of ​​the supporting plate 19.

[0047] By adopting the above technical solution and based on the above embodiment, in the process of the heating plate 3 drying the drying mechanism 4 in the circulating rotation state to dry and regenerate the silica gel desiccant 44, the heating plate 3 heats the air inside the equipment box 1, and uses the hot air to further dry the silica gel desiccant 44. However, if the hot air in the equipment box 1 rises through the hollow supporting plate 19, it will also heat the camera body 18 and have an impact. Therefore, in order to avoid the impact of high temperature on the camera body 18, before drying and regenerating the drying mechanism 4, the user controls the winding rod 25 to rotate by driving the motor 27 to rewind the hollow elastic metal mesh layer 261 on the lower side of the supporting plate 19. In this process, the thermal insulation film layer 262 wrapped around the outer surface of the unwinding rod 24 inside the unwinding drum 23 is unwound and stretched, and then the rotation of the unwinding rod 24 and the coil spring 221 inside the pre-tightening cylinder 22 After pre-tightening, the thermal insulation film layer 262 is stretched to the lower side of the carrier plate 19 to completely block the carrier plate 19, thereby isolating the influence of the rising hot air generated during the heating process on the camera body 18. After the drying and regeneration work is completed, the driving motor 27 is flipped. At this time, the unwinding rod 24 is flipped under the action of the coil spring 221 in the pre-tightened state, and the thermal insulation film layer 262 is rolled up, and the grid layer 261 is stretched and displaced to the lower side of the carrier plate 19 for normal ventilation and drying work. The present invention, by designing the winding drum 21 and the unwinding drum 23 in conjunction with the transmission mechanism 5, can further isolate the heat from the cavity on the lower side of the carrier plate 19 during the process of drying and regenerating the silica gel desiccant 44 in the drying mechanism 4 by the heating plate 3, thereby reducing the influence of the high-temperature drying silica gel desiccant 44 temperature on the camera body 18 on the upper side of the carrier plate 19, thereby improving the overall working efficiency of the device.

[0048] As an embodiment of the present invention, Figure 3 and Figure 7As shown, the transmission mechanism 5 includes a pulley 51, a main transmission wheel 53 and a ratchet assembly 54 which are arranged on the rear end face of the equipment case 1 in sequence from top to bottom, wherein the pulley 51 and the ratchet assembly 54 are fixedly connected to the internal transmission shaft 16 and one end of the roller 41 of the equipment case 1 respectively, and the main transmission wheel 53 is located between the pulley 51 and the ratchet assembly 54. Two belt grooves are provided on the outer surface of the main transmission wheel 53, and a belt body 52 is provided between the main transmission wheel 53, the pulley 51 and the ratchet assembly 54. The main transmission wheel 53 is connected to the pulley 51 and the ratchet assembly 54 through the belt body 52, and the main transmission wheel 53 transmits power to the external motor equipment.

[0049] By adopting the above technical solution, the external motor drives the main transmission wheel 53 to rotate. At this time, the main transmission wheel 53 drives the ratchet assembly 54 and the pulley 1 51 to rotate at the same time through the belt body 52. ​​Due to the action of the ratchet assembly 54, the drying mechanism 4 connected to the ratchet assembly 54 inside the equipment box 1 does not rotate. At this time, the transmission shaft 16 connected to the pulley 1 51 drives the fan 14 to rotate counterclockwise, which ensures normal ventilation and heat dissipation inside the equipment. When it is necessary to dry and regenerate the silica gel desiccant 44 in the drying mechanism 4, the external motor drives the main transmission wheel 53 to rotate clockwise, and then drives the roller 41 to rotate under the action of the ratchet assembly 54.

[0050] As an embodiment of the present invention, Figure 7 As shown, the ratchet assembly 54 includes a ratchet disc 545 fixedly connected to the rear end of the roller 41, and the outer surface of the ratchet disc 545 is annularly and equidistantly distributed with locking pieces 541, and the outer surface of the ratchet disc 545 is rotatably connected to a turntable 543, and the inner surface of the turntable 543 is provided with a locking groove 544, and one end of the locking piece 541 extends to the inside of the locking groove 544, and the outer surface of the turntable 543 is fixedly connected to the second pulley 542, and the belt body 52 is wound around the outer surface of the second pulley 542, and a ventilation port 17 is provided at the bottom of the equipment box 1, and the ventilation port 17 is designed in a grid-like structure, and support legs are fixedly connected on both sides of the bottom of the equipment box 1.

[0051] By adopting the above technical solution, when the external motor drives the main transmission wheel 53 to rotate counterclockwise, the pulley 2 542 rotates counterclockwise to drive the turntable 543 to rotate. At this time, the locking piece 541 is relatively displaced along the locking groove 544 and will not drive the ratchet plate 545 to rotate. When the pulley 2 542 rotates counterclockwise, the turntable 543 carries the locking groove 544 and the locking piece 541 to hit each other, thereby driving the ratchet plate 545 to rotate, and further driving the roller 41 connected to the ratchet plate 545. The present invention designs the ratchet assembly 54 to enable the transmission mechanism 5 to drive the fan 14 to ventilate and dissipate heat inside the equipment box 1 when the equipment is normally used. When the drying mechanism 4 needs to be dried, it rotates in the opposite direction and then drives the drying mechanism 4 to circulate and rotate for drying and regeneration through the ratchet assembly 54, and causes the fan blades to rotate in the opposite direction, so that the hot gas generated by the internal drying flows out, which not only increases the drying efficiency, but also prevents the accumulation of high-temperature gas from affecting the normal operation of the camera body 18 inside the equipment box 1.

[0052] Working principle: When the equipment is in normal working state, the main transmission wheel 53 is driven by an external driving device to rotate, and then the transmission shaft 16 and the drying mechanism 4 are driven to operate. The external motor drives the main transmission wheel 53 to rotate. At this time, the main transmission wheel 53 drives the ratchet assembly 54 and the pulley 1 51 to rotate at the same time through the belt body 52. ​​Due to the action of the ratchet assembly 54, the drying mechanism 4 connected to the ratchet assembly 54 inside the equipment box 1 does not rotate. At this time, the transmission shaft 16 connected to the pulley 1 51 drives the fan 14 to rotate counterclockwise, which is normal for ventilation and heat dissipation inside the equipment, and ventilates the outside air. The air is introduced through the ventilation slot 15 and filtered by the filter 13 into the equipment box 1 for filtration. Then, the air inside the equipment box 1 is ventilated and alternately heated and cooled with the outside cold air to cool the camera body 18. When the outside air enters the equipment box 1, it will first contact the drying mechanism 4, which uses the hollow structure of the conveyor belt 43 and the silica gel desiccant 44 inside the shell 42 to dry the air entering the equipment box 1. The shell 42 absorbs moisture from the water in the air to prevent excessive moisture from adhering to the outer surface of the equipment box 1 and the camera body 18 and damaging the equipment. When the water content of the silica gel desiccant 44 reaches a certain proportion ( Select color-changing silica gel desiccant and select drying and regeneration through personnel observation or select drying and regeneration according to the length of the use cycle). When the silica gel desiccant 44 in the drying mechanism 4 needs to be dried and regenerated, the external motor drives the main transmission wheel 53 to rotate clockwise, and then drives the roller 41 to rotate under the action of the ratchet assembly 54. When the external motor drives the main transmission wheel 53 to rotate counterclockwise, the second pulley 542 rotates counterclockwise to drive the turntable 543 to rotate. At this time, the engaging piece 541 moves relatively along the engaging groove 544 and will not drive the ratchet disc 545 to rotate. When the second pulley 542 rotates counterclockwise, , the turntable 543 carries the engaging groove 544 and the engaging piece 541 to abut against each other, thereby driving the ratchet disc 545 to rotate, further driving the roller 41 connected to the ratchet disc 545, thereby causing the conveyor belt 43 wrapped around the outer surface of the roller 41 to rotate, and then the heating plate 3 and the external power supply are electrically conductive to operate to heat the air inside the equipment box 1, and then the conveyor belt 43 rotates to carry the shell 42 and the silica gel desiccant 44 filled inside. The shell 42 circulates through the areas of the heating plates 3 on both sides, and then the silica gel desiccant 44 particles are dried and regenerated, and the roller 41 stops rotating until the silica gel desiccant 44 is regenerated;

[0053] During the process of drying the drying mechanism 4 in the circulating rotation state by the heating plate 3 so as to dry and regenerate the silica gel desiccant 44, however, if the hot air in the equipment box 1 rises through the hollow structure supporting plate 19, it will also heat the camera body 18 and have an impact. Therefore, in order to avoid the impact of high temperature on the camera body 18, before drying and regenerating the drying mechanism 4, the user controls the winding rod 25 to rotate by the driving motor 27 to rewind the hollow elastic metal mesh layer 261 on the lower side of the supporting plate 19. During this process, the thermal insulation film layer 262 wrapped around the outer surface of the unwinding rod 24 inside the unwinding drum 23 is unwound and stretched, and then the rotation of the unwinding rod 24 and the pre-tightening spring 221 inside the pre-tightening drum 22 are pre-tightened, and then the thermal insulation film layer 262 is stretched to the lower side of the supporting plate 19 to rewind the supporting plate 19. The plate 19 is completely blocked, thereby isolating the influence of the rising hot air generated during the heating process on the camera body 18. After the drying and regeneration work is completed, the driving motor 27 is flipped. At this time, the unwinding rod 24 is flipped under the action of the coil spring 221 in the pre-tightened state, and the thermal insulation film layer 262 is rewound, and the mesh layer 261 is stretched and displaced to the lower side of the carrier plate 19 for normal ventilation and drying work.
